Best jewellery engraver entry level

[magicniner]

The problem with CNC is the set up time they can do the jobs freehand quicker than plugging it in.

You've not done that then?
I have and I have to inform you that if 2D engraving with corners the diameter of your cutter at the set depth is acceptable that's fine, if you want deep engraving with sharp corners then the only way you get that is with a 3D tool path which lifts at the corners - a V-Carve type tool path - and that is CNC
